A.1.2. Radiated Emission Measurements

Measurement performed according to Clause 6.4, 6.5, 6.6 in ANSI C63.10-2013 and II.G.4, II.G.5, II.G.6 in KDB 789033.

The radiated emission test is performed in a semi-anechoic chamber. The EUT was placed on a non-conductive table with 80cm above the ground plane for measurement below 1GHz and 1.5m above the ground plane for measurement above 1GHz. The measurement antenna was placed at a distance of 3 meters from the EUT. The test is carried out on both vertical and horizontal polarization, and only the maximization result of both polarizations is kept. During the test, the turntable is rotated from 0° to 360° and the measurement antenna is moved from 1m to 4m to get the maximization result. The maximization process was repeated with the EUT positioned in each of its three orthogonal orientations.

Standard Limit (dBm)

Set RBW = 1 MHz.

Set VBW ≥ 3 MHz.

Number of points in sweep ≥ 2 × span / RBW.

Sweep time = auto.

Trace average at least 100 traces in power averaging (rms) mode; however, the number of traces to be averaged shall be increased above 100 as needed to ensure that the average accurately represents the true average over the on and off periods of the transmitter. Compute power by integrating the spectrum across the EBW (or, alternatively, the entire 99% occupied bandwidth) of the signal using the instrument's band power measurement function with band limits set equal to the EBW (or occupied bandwidth) band edges. If the instrument does not have a band power function, sum the spectrum levels (in power units) at 1 MHz intervals extending across the EBW (or, alternatively, the entire 99% occupied bandwidth) of the signal. Add 10 log (1/x), where x is the duty cycle.

18000-265001MHz/3MHz
26500-400001MHz/3MHz

A.5.4 Calculation

  1. The measurement results reported below is calculated by: Measurement Results (dBμV/m) = Pmeasurement (dBμV) + Cable Loss(dB) + Antenna Factor (dB/m) Where: Pmeasurement is the field strength recorded from the instrument
  2. Convert the resultant EIRP level to an equivalent electric field strength using the following relationship: E=EIRP- 20log (D) +104.77 Where: E is the field strength in dBμV/m D is the measurement distance in meters EIRP is the equivalent isotropically radiated power in dBm

Test note

  1. The EUT is operating at its maximum duty cycle and its maximum power control level.
  2. Investigation has been done on all modes and modulations/data rates. Only the radiated emissions of the configuration that produced the worst case emissions are reported in this section.
  3. Spurious emissions for all channels were investigated and almost the same below 1GHz. According to FCC 47 CFR §15.31, emission levels are not report much lower than the limit by over 20dB.
  4. The test is carried out on both vertical and horizontal polarization and only maximization result of both polarizations is kept.
  5. EUT in each of three orthogonal axis emissions had been tested out only the worst case (axis data) recorded in the report.
  6. Measurement frequencies were performed from 9 kHz to the 10th harmonic of highest fundamental frequency or 40GHz, whichever is lower.
  7. No spurious emissions were detected within 20dB of the limit below 30MHz. OFS and semi-chamber comparison testing had been performed and the result came out very similar. (KDB 414788)

A "reference path loss" is established and the ARpl is the attenuation of "reference path loss", and including the gain of receive antenna, the gain of the preamplifier, the cable loss. PMea is the field strength recorded from the instrument.

A.5. Radiated Unwanted Emission

A.5.1 Limits

Unwanted Emissions in the unrestricted bands shall not exceed the limits that shown in 15.407:

StandardLimit (dBm/MHz)
at the band edge27
FCC 47 CFR Part 15.407at 5 MHz above or below the band edge15.6
at 25 MHz above or below the band edge10
at 75 MHz or more above or below the band edge-27

Note: Increasing linearly from point to point.

In addition, radiated emissions which fall in the restricted bands, as defined in § 15.205(a), must also comply with the radiated emission limits specified in § 15.209(a) (see § 15.205(c)).

Frequency (MHz)Field strength(µV/m)Measurement distance (m)
0.009-0.4902400/F(kHz)300
0.490-1.70524000/F(kHz)30

A.5.3 Test Procedures

Radiated unwanted emissions from the EUT were measured according to ANSI C63.10 and KDB 789033 D02 v02r01.

Test setting

Frequency of emission (MHz)RBW/VBW
30-1000100kHz/300kHz
1000-40001MHz/3MHz
4000-180001MHz/3MHz
18000-265001MHz/3MHz
26500-400001MHz/3MHz

A.5.4 Calculation

  1. The measurement results reported below is calculated by: Measurement Results (dBμV/m) = Pmeasurement (dBμV) + Cable Loss(dB) + Antenna Factor (dB/m) Where: Pmeasurement is the field strength recorded from the instrument
  2. Convert the resultant EIRP level to an equivalent electric field strength using the following relationship: E=EIRP- 20log (D) +104.77 Where: E is the field strength in dBμV/m D is the measurement distance in meters EIRP is the equivalent isotropically radiated power in dBm

Test note

  1. The EUT is operating at its maximum duty cycle and its maximum power control level.
  2. Investigation has been done on all modes and modulations/data rates. Only the radiated emissions of the configuration that produced the worst case emissions are reported in this section.
  3. Spurious emissions for all channels were investigated and almost the same below 1GHz. According to FCC 47 CFR §15.31, emission levels are not report much lower than the limit by over 20dB.
  4. The test is carried out on both vertical and horizontal polarization and only maximization result of both polarizations is kept.
  5. EUT in each of three orthogonal axis emissions had been tested out only the worst case (axis data) recorded in the report.
  6. Measurement frequencies were performed from 9 kHz to the 10th harmonic of highest fundamental frequency or 40GHz, whichever is lower.
  7. No spurious emissions were detected within 20dB of the limit below 30MHz. OFS and semi-chamber comparison testing had been performed and the result came out very similar. (KDB 414788)

A "reference path loss" is established and the ARpl is the attenuation of "reference path loss", and including the gain of receive antenna, the gain of the preamplifier, the cable loss. PMea is the field strength recorded from the instrument.

Conclusion: PASS

A.6. AC Powerline Conducted Emission

A.6.1 Summary

All AC line conducted spurious emissions are measured with a receiver connected to a grounded LISN while the EUT is operating at its maximum duty cycle, at maximum power, and at the appropriate frequencies. All data rates and modes were investigated for conducted spurious emissions. Only the conducted emissions of the configuration that produced the worst case emissions are reported in this section.

A.6.2 Method of Measurement

See Clause 6.2 of ANSI C63.10 specifically. See Clause 4 and Clause 5 of ANSI C63.10 generally. The conducted emissions from the AC port of the EUT are measured in a shielding room. The EUT is connected to a Line Impedance Stabilization Network (LISN). An overview sweep with peak detection was performed. The measurements were performed with a quasi-peak detector and if required, an average detector. The conducted emission measurements were made with the following detector of the test receiver: Quasi-Peak / Average Detector. The measurement bandwidth is:

Frequency of Emission (MHz)RBW/IF bandwidth
